VIBRATOR AT'IAGHMEN '1.

Application filed December 11, 1930. Serial No. 501,549.

My invention relates to electric magnetic vibrators such for instance. as 1s shown in my prior application Serial No. 268,609, filed April 9, 1928 for vibrator.

It is the principal purpose of thls 1nvent-ion to provide an attachment for vibrators of this character for use in vibrating the hand or, more strictly speaking the tips of the attachment which is the subject matter of this application, all the advantages of the rapid vibration of the electro-magnetic vibration may be obtained in combination with the advantages obtained by using the hand as the applicator.

More specifically it is a purpose of this invention to provide in combination with the electro-magnetic vibrator a device which may be readily attached to the armature thereof and which serves as a backing for the hand to communicate the vibrations ofthe armature to the finger tips of the hand.

In providing an attachment of this character, I have found that it is best to attach the attachment in a certain definite position relative to the armature and to so construct the same as to prevent detuning the armature to such an extent as to destroy the effectiveness of the vibrator.

I will describe the preferred form of my invention more specifically by reference to the accompanying drawings wherein Fig. 1 is a side view showing the'vibrator and attachment in conjunction with the hand of the operator;

Fig. 2 is a bottom plan view of the attach- Y armature which as shown is, secured at the rear nd o the re by means of'a spring 9.

indieatea generally at. 10

is used to control the operation of the vibrator which receives the operating current through the usual electric cord 11. The armature S is provided at its free end 12 with a mounting means consisting of a stud 13 rigidly connected to the armature which stud is interiorly screw-threaded to receive the usual massage tools. I prefer to make this stud rectangular in cross section for a purpose which will presently appear.

The attachment consists of an elongated spring plate-14 carrying a pair of cross bars 15 and 16 which cross bars are rigidly secured thereto in any suitable manner. These cross bars in turn support yielding backing members for the hand. As shown, these consist of a pair of disks 17 and 18 on the rear bar 15 which are constructed of rubber in the preferred form so as to give a yielding surface against which the back of the hand may be placed. The front bar 16 carries a single backing member 19 of a similar character. A plurality of coiled springs 20 and 21 are secured at their opposite ends to the ends of the bar 15 to form flexible receiving loops for the hand. Another pair of similar springs 22 and 23, are connected to the opposite ends of the bar 16 to receive two of the fingers of the hand and complete the attachment of the vibrating device to the hand. It is obvious that the hand securing loops may be of any suitable material other than the coiled springs described.

' The plate 14 is preferably of spring mate rial and isslightly curved as shown in Fig. 1 to conform to the natural contour of the back of the hand. Bars 15 and 16 also preferably are slightly curved intermediate their ends so as to fit more comfortably to the back of the hand.

In order to insure rigidity between the mounting stud 13 and the plate 14, I secure the plate by means of a screw bolt 24 and alsoturn the end 25 thereof down over the flat front face of the stud. This forms an effective bracing construction for the plate 14 and serves to. align it with; the armature so that it extends back toward the rear end of't'he vibrator a line substantially? parallel-"cc the The, length of the platen is. prefe erably made such that the rear end thereof terminates substantially at the rear end of the vibrator.

These *ibrators are provided in the first instance with an armature that is suitably tuned to the electro-magnet employed so as to give the best operation with the ordinary massaging tool. Now in applying the attachment, it is obvious that the same is somewhat heavier and more unwieldy than the massage tool. This has a tendency to detune the armature and thus make the vibrator less eilicient.

I find, however, that by utilizing spring material in the construction of the plate 14 and extending the same rearwardly in the manner shown and attaching it at one extreme end to the armature, I avoid a great deal of the detuning eti'ect of the attachment. This construction also communicates the vibration principally to the tips of the fingers and very little to that portion of the hand which is secured to the bar 15. The vibration takes place in the form of a more or less angular motion about the back end of the plate 14; thus giving the maximum range of movement to the tips of the fingers with very little movement to the main portion of the hand. This is no doubt owing to a combination of the mounting of the armature at one end and the extending of the plate from its point of securemcnt at the free end of the armature toward the fixed end of the armature. The armature thus relieved from the effort of vibrating the back end of the spring 1 In fact, the spring 9 which is the proper stiffness to tune the armature hen using the regular standard applicators 1n the stud 26 has the spring effect of spring 14 added to it when the new attachment and the hand are connected to it and thus the additional spring elli'cct of 14; takes care of tuning the additi cnai weight of the hand.

From the above description, it is believed that the construction and operation of this device will be clear to those skilled in this art and the advantages thereof readily ap parent. It is obvious that various minor modifications can be made from the exact details shown and described without departing from the scope of the invention.

Having thus described my invention, what I claim as new and desire to secure by Lette s Patent is:
